Performing the above does not necessarily mean to check for faulty injectors. It is to locate any cylinder that is not firing correctly. It could be a fault with compression.
Did all cylinder shows similar amount of difference in engine running condition or did any one or more showed a more significant difference?
Do you have coolant losses issues and did engine ever overheated badly?
White smoke is usually due to non firing conditions or timing is too advanced. It could also mean a minimal amount of water is getting to the cylinders, either due to a bad head gasket or bad cylinder head.
